MEYERHOEFER 2,170,031 i CORE MOUNTING Filed July28, 1957 Patented Aug. 22, 1939 UNITED STAT-Es APATENT OFFICE 2,170,031com: -MoUNTiNG poration of New York Application July 2s, 1937, 'serialNo. 156,250 4 claims. w1. 257-137) This invention relates to afunctionally and structurally improved core'mounting, and in its morespecific aspects aims to provide a structure of this nature which willbe of particular value 5 when employed in connection with heat exchangeapparatus wherein uid under temperature differential is depended upon toheat or cool an enclosure such as the body of a motor vehicle.

It is an object of the invention to furnish a structure of this natureand wherein the entire core or uid receiving assembly is mounted so thatit is cushioned against shocks. As aconsequence, the danger of damage tothe core with resultant leakage is reduced to a minimum.

A further object of the invention is that, of furnishing a structure ofthis character in which the noises incident to the passage of uidthrough the core will be minimized in so far as possible. Accordingly,the occupants of the enclosure in which the heat exchange device ispositioned will not be subject to annoying and distracting noisesincident to this factor.

A still further object is that of providing a mounting which will becushioned against the transmission of noises.' acoustically perceptiblevibrations, etc., from the motor, so that diiculties in this connectionwill also be overcome.

An additional object is -that of providing a structure embracingrelatively few parts, each individually simple and rugged inconstruction, these parts being capable of production and use at minimumexpense and having a life equal to that of the unit with which they areassociated.

With these and other objects in mind, reference is had to the attachedsheet of drawings illustrating one practical embodiment of theinvention, and in which: y

Fig. 1 is a top plan view of a heat exchange unit with certain of theparts broken away to 40 disclose underlying construction; and

Fig. 2 is arear view of such unl with parts similarly broken away. A"

In these views, the numeral 5 indicates a core which may include upperand lower header portions connected by a heat exchange structure such asa sexies of cells, tubes, or otherwise. The

'headers of the core are coupled to a source ci Huid, as, for example,by tubes 6, one of -rwhich is conveniently provided adjacent one end ofone header, while the other is preferably disposed adjacent the oppositeend of the second header.

f 'I'he core is enclosed within a casing 7, con- 'venlently formed ofsheet metal, and which may have applied to its rear face a shroud plate8.

' 55 In line with the latter 'and the heat exchange structureaforedescribed, a fan 9 may be mounted. This fan is secured to the shaftof .a motor I0, which may also conveniently drive a blower wheel II,enclosed within a casing I2. Extending from this casing is a duct I3,through which air dis- 5 tributed by the blower Wheel is impelled. 'I'heair drawn through the heat exchange core by fan 9 may convenientlystrike against a deector ring I4, which may form a continuation of theforward wall of casing I2. The latter may also be l@ inclined outwardlyand rearwardly, so that air moving from the fan is deflected outwardlyand then forwardly by ring IB.

Secured to casing 7, preferably by being coupled to .plate 8, aremounting brackets I5. These are l@ formed with openings through whichthe Shanks or bolts I6 are extended, for the purpose of securing thestructure to a suitable surface. These bracketsmay also support amounting member I'I to which the motor I0 is coupled. 20 Y The foregoingstructuregenerally stated-is disclosed and described in applicationsheretofore led, and, except Where indicated in the appended claims,forms no part of the present invention. However, it will be observedthat, as shown, the 25 brackets I5 are provided with straps I8, havingopenings through which tubes 6 project. These openings mount grommetsI9, of rubber or similar material, which are in firm contact with thetubes 6. Thus, while these tubes are adequately sup- 30 ported, therewill be lno danger of objectionable contact occurring between the sameand the straps.

Moreover, the shroud plate 8 is coupled to casing l, preferably bybosses 20, extending rear- 35 wardly from the latter, and the outer endsof vwhich are formed with screw-threaded recesses.

Screws or bolts 2I have their shanks extended through openings in plate8 and into these recesses. As a consequence, a contractible struc- 40ture is furnished which, as it acts against the core assembly, willclamp the latter against movement. The casing 1, being formed of metal,it is apparent that it should not directly contact the core.

Thus, as shown, the core should have a width and 46 height less than thecorresponding dimensions of the shell and casing. y

Moreover, the shroud plate is formed with extensions 22 which projectinwardly of such plate and provide transversely extending mounting 50portions adjacent their inner ends. These mounting portions may each beformed with an opening. Thus, rods or cushions 23, of rubber or similarmaterial, may have their reduced end portions extending through theseopenings, with their opposite ends bearing against the headers or othersuitable portions of the core assembly. The shell or casing 1 is alsoformed, in its inner face, with a series of projections 2l, which mayconveniently be integral therewith. Each of these projections receives acollar or sleeve 25, again preferably formed of rubber, and it is thusapparent that the entire core assembly is confined within shell 1 by astructure which acts as a floating suspension. In tightening bolts orScrews 2|, it is apparent that a suiciently high degree of pressure willbe exerted, so' that the cushioning elements clamp the core againstsidewise movement. Such movement will further be guarded againstincident to the mounting of tubes 6.

In certain instances, collars 25 may be dispensed with, or there may beprovided, auxiliary thereto. a rubber strip or channel member 26,mounted upon the inwardly extending flange or projection of shell 1.This strip, or its equivalent, bears against the front face of the coreassembly, and either acts as a substitute for the collars or tubes, ormay function auxiliary thereto. While any desired number of cushioningelements might be employed, it is preferred that four pairs of the samebe utilized. 'I'his will provide two collar members and cushions foreach of the core headers, and it has beenfound that such an arrangementof the parts is ideal under commercial conditions. It is, of course,understood that, in lieu of single extensions each supporting two rubbercushioning elements, extensions individual to those elements mightreadily be employed.

Thus, among others, the several objects of the invention as specificallyafore noted are achieved. It will be appreciated that numerous changesin construction and re-arrangement of the parts might be resorted towithout departing from the spirit of the invention as defined by theclaims.
